Segfault when process exits with active sweep thread [CORE5197] #5478

Open firebird-automations opened 8 years ago

firebird-automations commented 8 years ago

Submitted by: @AlexPeshkoff

Is duplicated by CORE6338

In case when process exits when sweep thread has not yet attached to database (i.e. very fast) process does not wait for sweep thread to complete and begins cleanup with sweep starting which almost for sure causes access violation.

Hello!

Can this cause DB corruption? CS and SC both are affected?

This bug has no specific 'features' corrupting database, but certainly some chances to have DB corrupted are present. Must say I've never noticed it when debugging.

CS is more affected - it has much more chances to exit a process when sweep thread is starting. But SS may be affected too.

First fix did not pass regular tests
